MATTHEW R. MARKS AND ALFRED IVERSON, OF ORLANDO, FLORIDA.

AXLE-LUBRICATOR.

SPECIFICATION forming part of Letters 'Patent No. 241,500, dated Mayl 17, 1881.

` Appiication flied october 21,1880. (Nomads.)

To all whom it may concern Be it known that we, MATTHEW Ii. MARKS and ALFRED IvERsoN, of Orlando, in the county of Orange and State of Florida, have invented cert-ain new and useful Improvements in Axle-Lubricators and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Figure 1 is a vertical longitudinal sectional view of a wheel-hub with our improved lubricator applied. Fig. 2 is a perspective of the lubricator'detached. Fig. 3 is a `longitudinal sectional view of the lubricator-case and the internal mechanism.

This invention has relation to axlelubrica tors 5 and it consists of the improved features of construction and combination hereinafter fully described, and particularlypointed out in the claim.

In the drawings, A represents the spindle, and B the hub, of a vehicle. The hub is constructed of wood or metal, and of any approved pattern, and the lubricator is inserted into a screw-threaded aperture, O, so that when the valve in the lubricator is pressed down the oil will ow around the valve, down the channel thus opened to the spindle, and when the pressure upon the piston J is removed the spring E will force the valve up into the nozzle and close the mouth of the lubricator. When the pressure has been removed and the valve closed the oil cannot escape through the channel by which it was introduced, and dust and the like is excluded therefrom. The valve may be constructed in any well-known form, the method illustrated being preferable.

Withinthe nozzle G is a tube, H, connected t0 the upper or convex side of the valve D,

and a piston, J, connected to the lower or un- Vder side of said valve, slides in the cylinder or case K, and is held in its normal position by the spring E. The spout or nozzle of the oil-can is used to depress the tube H, which forces the valve D down, and also the tube, so that the opening h, near the lower end thereof, will come inside ot' the cylinder or case K, so that the oil will flow through said tube to the oil-chamber L formed around the piston, and passes through the perforated diaphragm M around the spring and to the spindle, as will be readily understood from the drawings.

We are aware that a cylinder or case having a nozzle at the upper end and an interior sprin g-valve for closing said nozzle is common in aXle-lubricators, and such we do not wish to be understood as claiming, broadly, as of our invention.

Having thus t'ullyldescribedfour,invention, what we claim as new, anddesire to secure by Letters Patent, is

The herein-described aXle-lubricator, composed ot the cylinder or case K, adapted for insertion in the wheel-hub of av vehicle, and having nozzle G at the upper end thereof, the valve D, arranged to close said nozzle, and having a tube, H, tittingin the said nozzle, and having side opening, h, the piston J, connected to the lower or under side of said valve, and provided at its lower end with a perforated diaphragm, M, and operating-spring arranged below said daphragm,-as specified.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence of two witnesses.
